The book progresses by first laying a foundation of core psychological principles, supported by research on cognitive biases. It then applies these principles to specific, contentious issues such as climate change and political polarization, presenting case studies and empirical data. Finally, Facts Vs Beliefs offers strategies for bridging the gap between factual information and belief systems, emphasizing critical thinking and open-mindedness. It argues that intellectual humility is key to navigating today's information-saturated world.
